Cardiac Arrhythmias

Cardiac arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heartbeat. Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress.
